Additional
Camera Features
The PowerShot Pro90 IS offers a number of additional features including Movie Mode.
While in this mode, the Pro90 IS can record a QVGA (320 x 240 pixel) digital movie
clip with audio at 15 frames per second for approximately 30 seconds. Saved as an
AVI file, the movie can then be played back on the camera's LCD monitor, a TV monitor
using the supplied audio-video cable or on a compatible personal computer.
The PowerShot Pro90 IS also incorporates a series of Programmed Image Control modes
that are easily set by using the Mode Dial on the top of the camera. In the Auto
mode, the camera sets all the parameters for exposure while the user simply sets
the resolution and compression settings. In the Pan Focus mode, the lens is set to
its wide-angle focal length and hyperfocal distance to achieve the greatest depth-of-field.
The Portrait mode automatically sets a larger aperture to achieve minimum depth-of-field
for a blurred background. The Landscape mode sets the optimum aperture for expanded
depth-of-field from foreground to background while continuing to focus on the main
subject. In the Night Scene mode, the camera properly exposes the foreground subject
with flash and sets a slow shutter speed for correct exposure of illuminated backgrounds.
The Black-and-White mode allows users to create beautiful black-and-white images.
Stitch Assist helps users create seamless panoramas by using the LCD monitor to align
images while shooting.
In the Creative Zone of the Mode Dial, users can select between Program, Shutter
Priority, Aperture Priority or Manual exposure control. These settings also provide
access to a host of other camera features such as single or continuous autofocus,
spot metering and AE lock, various forms of exposure compensation, plus manual and
custom white balance settings and much more.
Superior Handling and Ease of Use
Digital photographers at any level of skill will find it easy to maneuver around
the camera's auto, manual and creative shooting modes. Similar to Canon's EOS System
cameras, the User Interface (UI) is clear and concise with graphical icons that are
universally understood. The main dial of the camera is used to set the camera for
picture-taking, playback and PC download, while the Mode Dial is used to set the
camera's 12 EOS-based picture-taking modes such as Auto, Programmed Image Control
Zone, and Creative Zone. Popular features such as IS on/off, metering pattern, exposure
compensation and flash have their own buttons. A four-position Omni Selector is used
to change menu settings and select images during playback.
The PowerShot Pro90 IS is powered by a rechargeable lithium-ion battery that has
more capacity but less weight than nickel metal-hydride, with no memory effect.
